Expanding Bicep on a Pattern

Biceps impact sleeve fit and appearance. Expand bicep on pattern for better garment fit and comfort.  Expanding bicep on pattern ensures better, comfortable fit for shirts, jackets, or dresses with sleeves.

If you find that the bicep area of your sleeve pattern is too tight or too loose, you may need to make some adjustments to the size. Fortunately, this is a relatively simple process that can be done with just a few measurements and some basic math.

Where to start.

Start by measuring the bicep circumference on your sleeve pattern. Wrap a tape around the widest part below the sleeve cap. Record this measurement for pattern adjustment.

Too tight?

If the bicep area is tight, add extra room to the pattern. Calculate by subtracting your bicep circumference from the sleeve pattern. For instance, if your bicep is 33cm and the pattern is 31cm, add 2cm.

Too loose?

If the bicep area is loose, reverse the process. Subtract the difference between your bicep and sleeve pattern, then divide by two.  This will give you the amount of space that you need to remove from each side of the sleeve.

Making adjustments to the bicep area of a sleeve pattern can seem intimidating at first, but with a little practice, it becomes easier. By taking accurate measurements and carefully redrawing the pattern, you can ensure that the sleeves of your garments fit comfortably and look great.
